JEEP GRAND CHEROKEE DIESEL: Jeep’s top-selling Grand Cherokee marks the first major expansion into diesel in the U.S. by a mainstream SUV maker, showing the potential for boosting power and fuel economy. The 3-liter, EcoDiesel V-6 engine promises 240 horsepower and 7,400 pounds towing. It expects 20 mpg city and 28 mpg highway for 4x4 models.

KIA CADENZA: Kia is moving into the North American premium sedan market with the 2014 Cadenza, aiming for buyers looking in the gap between mainstream and luxury. The South Korean automaker describes the sedan as having elements of European design, which help define the higher-end market. It will be offered with Kia’s most powerful V-6 engine.

CADILLAC ELR: The ELR has the same battery and gas-powered generator as the Chevrolet Volt. It has angular lights and fenders like other new Cadillacs, but in a more sloped, forward-leaning aerodynamic look.

VOLKSWAGEN CROSSBLUE: VW might get into the midsize SUV market. It would be a first: a plug-in hybrid SUV with a diesel engine and two electric motors. In electric mode, it would get the equivalent of 89 miles per gallon.

FORD ATLAS CONCEPT: Ford’s show truck hints at the 2015 F-Series pickup. The Atlas has a chiseled design and a bigger, more elaborate grille. Atlas emphasizes fuel economy. Shutters on the grille and wheels close automatically, improving aerodynamics. The truck weighs several hundred pounds less than the current model.
